The goal of this bachelor’s thesis is to investigate how the changes in the values of the water scrubbing simulator parameters affect the purity of methane. These investigations are performed by utilizing design of experiments and by analyzing their results.
The designs of experiments used in this bachelor’s thesis are the Taguchi method and the full factorial design. The Taguchi method is used to examine the main effects of the parameters by utilizing graphs and the results gained from the full factorial design are used to form a regression model, which is then analyzed.
Amongst the results gained from this investigation, the most important fact was the knowledge of the control factors that have the most significant impact on the response compared with the noise factors. If the control is performed well, the water scrubbing process can be made to be very stable in order to minimize the noise factors.
